Quick update:
unfortunately, as I expected the P&L is showing wrong profits, I did manual calculations and found that my gains are higher than what PNL shows.
Improving ideas:
From my observation on small TF like 5m or 3m, usually, the small dumps are between 3% up to 8%.
So I was wondering can we increase the distance between the first 3 DCA rounds? for example first DCA occurs after 1.5% down in the price (the current setting is around 0.5%), second & third one each occurs after an extra 1% down (the current setting is around 0.75%), the rest can be the same as the current setting.
I think if my idea is applicable then I can higher my TL and down the DCA rounds to 10 or 12 without worrying about the big dumps
